Granted: 1898-05-07
Abstract: 14,935. Bostock, R. June 21. Signals on engines; indicators and repeaters, signal contacts, mechanical; contacts, electric; signalling approach of trains.-Relates to means for signalling to the enginedriver whether the line is " clear" or " blocked," so obviating the use of fog signals, and enabling the ordinary signals, except the " home signal, to be dispensed with, if desired. Fig. 1 shows the indicator employed on the engine. This comprises a suitable number of miniature semaphore arms 1, which are connected by links 2 to, and are operated by, corresponding weights 3. These weights are normally supported by pivoted catches, each of which is connected to a corresponding shaft 15. Each shaft has a crank arm 17 carrying a vertically-movable rod 18, the lower end of which is provided with a striking- lever adapted to make contact with a corresponding inclined bar between the rails. The bars are raised into operative position, or lowered into inoperative position, by the signalman, either in conjunction with, or independently of, the ordinary signals, and are arranged so that, when in operative position, each will only operate its own indicator. When one of the rods 18 is raised by striking an operative bar, the corresponding weight 3 is released and falls, so operating the miniature semaphore 1. By the same movement, the weight also closes, between the contacts 5, 7, a circuit 9 through an electric bell, which continues to ring until the apparatus is reset by the driver. The resetting is effected by rotating the shaft 27 by means of the handle 26, the shaft 27 being provided with crank arms'28, which are connected by slotted links 29 to the weights 3. In the arrangement shown, one indicator is provided for the " home signal, two, showing respectively " ON and "OFF," for the "distant" signal, and one for showing whether the line is occupied by working gangs. The last-mentioned indicator is operated by a separate bar or lever fixed on the permanent way.

Title: Improvements in Engine Governors.
Inventor: HEPBURN GEORGE
Filed: 1899-01-28
Granted: 1899-03-04
Abstract: 1985. Hepburn, G., Taylor, J., and Evans, D. H. Jan. 28. Inertia governors.- Consists of means for enabling the speed of control to be regulated while the engine is running. The invention is especially applicable for preventing racing in marine engines. In Fig. 2, which shows the governor inside elevation, a is the inertia mass pivoted to the vertically - reciprocating frame c of the governor. In the example shown, control of the engine is effected through the action of pawls e, which are suitably adjusted whenever, owing to an increase of speed, the weight a lags behind the frame c during its downward stroke. According to the present invention, a regulable resistance is applied to the upward movement of the weight a, so that the speed at which the governor comes into action can be adjusted. The movement is opposed by a spring, (or air cushion), contained in a casing i supported by trunnions on the frame c. The pressure of the spring is regulated by the screw plug m, which is adjustable, while the engine is running, through worm gear and a flexible shaft connected to a stationary adjusting-wheel. A supplementary inertia mass u is provided for locking the weight a if any excessive acceleration of the engine occurs.

Title: Improvements in the Manufacture of Food Preparations.
Inventor: MERING JOSEPH FRIEDRICH FREIHE
Filed: 1900-06-25
Granted: 1901-06-01
Abstract: 11,524. Mering, J. F., Freiherr von. June 25. Food preparations.-Relates to food preparations containing the constituents of milk. The fat is removed from milk in a centrifugal machine, and is replaced by a corresponding quantity of the fat of yolk of eggs, added either alone or together with the remainder of the yolk. The milk deprived of fat, and the egg yolk or yolk fat, are evaporated to dryness either separately or after mixing. In order to render the food as digestible as human milk, the proportion of lactalbumen must be increased. This is effected by adding to the above preparation the dry product obtained by evaporating whey together with about 15 per cent, of skim milk or sweet milk, the evaporation of this mixture taking place without coagulating the albumen. The high proportion of chlorides or other soluble salts contained in the whey may be reduced by evaporating down the mixture of whey and milk until it contains 50 per cent. of water, and then allowing the mixture to cool in order to crystallize the milk sugar. The remaining liquid is removed by centrifugal means or otherwise. A nutritive flour can be prepared by mixing the aforesaid preparation with oat or wheaten flour &c., to which cane sugar or glucose may be added.

Title: Improvements relating to Sole-rounding Machines for Use in the Manufacture of Boots and Shoes.
Inventor: FLAGG GEORGE HENRY PECK
Filed: 1900-12-11
Granted: 1901-11-23
Abstract: 22.558. Lake, H. H., [Flagg, G. H. P.]. Dec. 11. Paring.-In sole-rounding machines, the knifesupporting parts are made adjustable for operating upon soles of different sizes, and brakes and clutches are provided in connection with the driving-shafts. The sole 3 to be rounded is clamped to a sole-holder 2 fixed upon the frame 1 of the machine, and the knife mechanism 8, 9, 11 is mounted upon a table 4, which is rotated from the driving-shaft 5 by the bevel gearing 6, 7. The holder 9 of the knife 8 is pivoted at 10 to a carrier 11, and is formed with a segmental rack 12, which engages with a spring- controlled pinion 14 on the carrier 11 to allow of the yielding oscillation of the knife holder 9. To accelerate the movement of the knife 8 along the sides of the sole-holder, and to retard its movement round the ends thereof, the carrier 11 is pivoted to the crank 15, which is journalled in a bearing 16 on the table 4, and is caused by the engagement of the pinions 18, 19 with the fixed pinicn 20 to complete two revolutions to one revolution of the table. A block 28 is adjustably connected to the crank 15 by a wrist-pin 21, and to the carrier 11 by a clamp 29, as shown in Figs. 5 and 6, so that the block forms, in. effect, an integral part of the carrier, which has a sliding connection by means of a groove 22 with a stud 23 on the table 4. The connections of the parts 15, 28, and 11 permit of the position of the carrier 11 being adjusted to suit the size of the sole under operation. The driving-shaft 5 is set in motion by depressing a hand-lever 116, which throws off the brake by withdrawing the roller wedge 120 from the contracted throat between the brake drum 117 and the shoe 118, and sets the clutch 102, 103 by means of a lug 115 on the lever 116 engaging an abutment 114 on a loose sleeve 112, which, through gearing and connections 111, 110, 109, 108, operates a sleeve 106 and causes the loosely-mounted driving-pulley 102 to engage the clutch 103 fixed on the shaft 5. As the shaft 5 rotates, a pin 131 on a cam-wheel 125 strikes an abutment on the sleeve 112 and releases the clutch. The movement of the shaft is, however, continued by the momentum of the parts until the dog 130 enters the recess 129 in the cam-wheel 125, when the roller wedge 120 is moved to reset the brake, and the rotation of the shaft is arrested. The relation of the gearing is such that the table 4 completes one revolution to one revolution of the cam-wheel 125, and the spring 123 prevents shock or jar during the braking movement.
